About this app

Riiiver is an IoT platform that connects products and services, expanding their possibilities and providing a new kind of user experience.
*Limited to Riiiver-compatible products and services.

~~Create and Use Your "iiideas"~~
With the Riiiver app, you can create and use functional items called "iiidea." Start by selecting one of the available iiideas that interests you and give it a try!

~~Make your “iiideas” come to life~~
You can create “iiidea” for the Riiiver platform. If you’ve ever wondered, “Wouldn’t it be great if I could do this?” or “Wouldn’t it be convenient to have that function?”, with Riiiver you can easily shape your ideas and make them a reality.

~~No special skills are needed!~~
Creating new functions with Riiiver is so easy. You don’t need to know anything about programming. All you have to do is put together a few functional modules (known as Pieces) in the app. Those with specialized knowledge (such as programming) can even create Pieces themselves. For more information on Piece development, please visit the Riiiver Developers website (https://developer.riiiver.com/).

~~The structure of Riiiver~~
In Riiiver, functions are called “iiidea.” They are assembled from the three types of Pieces: Trigger, Service, and Action.

To see a list of available Pieces, please check the following page:
https://app.riiiver.com/piece_list/piece_list.html

Riiiver is an open IoT platform service. As such, we plan to increase the number of compatible products in the future, so please stay tuned!

cool that you can try building your own interactions but still limited by preset puzzle pieces. built ideas don't go into your account until some random time either. tinkering around the last few weeks i find that i have to keep making useless ideas until it finally kicks them over to my citizen app to be able to actually try using them. this can take anywhere from 2-6 ideas, although I'm still not entirely sure of it isn't just a random time as I've gone a day or 2 before seeing them useabl

Since having my CZ Gen 2 Smartwatch hybrid, I have not been able to use the app, as it is entirely in Japanese; why!?
